Rosetree Very nice playing!! Kudos to you.
Reminds of what seems like 100 years ago I took a semester of applied organ at the University of RI with Professor George Kent
http://web.uri.edu/music/meet/george-kent/ Worked on 3 of the 8 preludes and fugues during the semester, the feet didn't cooperate as well as I would have liked, always found it easier to play in stocking feet. One thing I can never forget is being able to play the pipe organ on campus in Edwards Auditorium, what a grand instrument. It was mounted in the orchestra pit, you hit a button and the hyrdualics raised the organ and platform to the same level of the stage.
